A poll asked whether states should be allowed to conduct random drug tests on elected officials. Of 24,856 respondents, 58% said "yes." a. Determine the margin of error for a 99% confidence interval. b. Without doing any calculations, indicate whether the margin of error is larger or smaller for a 90% confidence interval. Explain your answer. Click here to view page 1 of the table of areas under the standard normal curve. Click here to view page 2 of the table of areas under the standard normal curve. SCH a. The margin of error for a 99% confidence interval is (Round to three decimal places as needed.) b. Without doing any calculations, indicate whether the margin of error is larger or smaller for a 90% confidence interval. OA. The margin of error will be about the same for a 90% confidence interval. OB. The margin of error will be larger for a 90% confidence interval. OC. The margin of error will be smaller for a 90% confidence interval. OD. There is insufficient information to determine the margin of error for a 90% confidence interval.
